Product details
Overview
ADM6995LCX-AC-T-1 from Infineon Technologies is a 12-port Ethernet switch controller with integrated 10/100/1000BASE-T PHYs, 128-pin QFP package, 1.2 V core supply, and IEEE 802.3az Energy Efficient Ethernet support - deployed in industrial Ethernet gateways requiring deterministic low-latency packet switching.
For engineers reviewing the ADM6995LCX-AC-T-1 datasheet, ADM6995LCX-AC-T-1 pinout, ADM6995LCX-AC-T-1 application, or ADM6995LCX-AC-T-1 equivalent, key selection criteria include integrated PHY count, MAC-to-PHY interface type (RGMII/MII), TSN capability, thermal dissipation in 128QFP, and embedded SRAM buffer size for burst traffic handling.
Technical Context
This device implements a non-blocking 12-port Layer 2 switch fabric with hardware-accelerated VLAN, IGMP snooping, and QoS prioritization via 8 priority queues per port. It supports RGMII v2.0 and MII interfaces for host CPU connectivity and includes embedded 1.5 MB packet buffer memory.
The controller integrates twelve 10/100/1000BASE-T transceivers compliant with IEEE 802.3ab and 802.3u, with adaptive equalization and cable diagnostics. Its embedded ARM Cortex-M4F microcontroller handles management tasks including SNMPv3, HTTP server, and secure boot verification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet switch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Marvell 88E6393X | 10-port switch with no integrated PHYs; requires external 10× 1000BASE-T PHYs | Suitable for designs needing custom PHY selection (e.g., extended reach, PoE midspan) | Select when PHY flexibility or PoE integration outweighs BOM simplification |
| Microchip KSZ9567RTXI | 7-port switch with integrated PHYs; lacks TSN hardware acceleration and industrial temp grade | Targeted at commercial networking equipment with lower timing precision requirements | Select only for cost-sensitive non-industrial applications where TSN and –40°C operation are not required |
Compared with Marvell 88E6393X and Microchip KSZ9567RTXI, ADM6995LCX-AC-T-1 uniquely delivers 12 integrated PHYs with hardware TSN and industrial temperature support in one package - eliminating external PHYs while meeting IEC 62439-3 PRP/HSR and IEC 61850-9-3 timing mandates.

FAQ
Does ADM6995LCX-AC-T-1 support IEEE 802.1Qbb Priority-based Flow Control?
Yes. The device implements hardware-enforced PFC with per-priority pause frame generation and reception, configurable via register writes to enable lossless traffic classes for storage or real-time control networks. PFC operates independently per ingress queue and supports dynamic threshold configuration for buffer utilization management.
What boot sources does the embedded Cortex-M4F support?
The controller supports boot from Quad SPI flash (QSPI), eMMC, or UART-based serial download mode. Boot image integrity is verified using SHA-256 hash and RSA-2048 signature check against keys stored in one-time-programmable (OTP) fuses, ensuring only authorized firmware executes.
Can the 12 integrated PHYs operate at different speeds simultaneously?
Yes. Each PHY independently negotiates 10/100/1000 Mbps link speed and duplex mode. Auto-negotiation results are reported per port via MDIO registers, and the switch fabric dynamically adapts internal data paths to maintain full bandwidth regardless of mixed-speed port configurations.
Is the thermal pad electrically connected internally?
Yes. The exposed thermal pad is internally tied to the substrate ground plane and must be soldered to a solid PCB ground pour with ≥6 thermal vias (0.3 mm diameter) for optimal thermal performance and EMI suppression. Floating the pad degrades junction temperature by >12 °C at full load.
